KGEA-MR KGEA-MR (Integrated connector) Middle Range Antenna LF for smart entry system. 

KGEA-MR (Integrated connector) Middle Range Antenna LF for smart entry system.

The Middle range antenna have been designed in order to reduce the number of antennas respect to the total number short antennas with equal or better performance reading distance and H-field around the whole vehicle.

Depending on the requirements and location of the antennas in the vehicle and taking into account its exposure to environmental
conditions, grade IP waterproof, mechanical robustness, etc.. PREMO offers from LPM technology, to Polyurethane, mixed LPM-resin and HPM.


New Middle Range Antenna with Low Pressure Technology (LPM)

- LPM is a well know technology in PREMO
- Vert fast to produce (No Curing needed)
- IP56 grade Waterproof

New Middle Range Antenna with PU-resin

- High mechanical robustness
- IP68 grade Waterproof


The main technical and economic advantages :
- Middle antenna (length until 200mm).
- External housing shape flat Material PBT-GF30% or PA66-GF30%
- Anchor points (Clips and pivot).
- High stability in temperature (-40ºC up to +85ºC).
- Resonant frequency adjusting below +/- 2kHz.
- Custom L-C value (F-Res: KGEA-MR) under demand
- This antenna is designed based on AECQ-200.

Operating Frequency @125Khz @25ºC @1Vac (L+C in series)

Antenna is measured in resonant mode.

The specification chart is a reference guide for the most common required values at working frequencies of 125 kHz, 20 kHz and 134.2 kHz. Any other inductance value at LF or tighter tolerances can be provided. Please contact our sales department for any inquiry.
